News Investigators/ Elon Musk on Thursday became the first person estimated to reach a net worth of 500 billion dollars. Forbes calculated Musk’s wealth at roughly 150 billion dollars more than Oracle co-founder Larry Ellison. The magazine later revised the estimate slightly down to 499.1 billion dollars. Musk’s wealth is harder to estimate than that of other billionaires because many of his companies are not publicly traded. Musk surpassed the 400 billion dollars mark in December 2024, amid investor speculation that Tesla would benefit from his connections to then-newly elected U.S. President Donald Trump.
